Abstract
A receiver for calculating its position according to a first transmitter, having a processor arranged to convolve: the probability density function representing the position of the first transmitter, sent by the first transmitter to the receiver; with the probability density function representing the likelihood that a transmission from the first transmitter will be successfully received at the receiver.
Claims13
A receiver for calculating its position according to a first transmitter, having a processor arranged to convolve:
- (i) the probability density function representing the position of the first transmitter, sent by the first transmitter to the receiver;
- with
- (ii) the probability density function representing the likelihood that a transmission from the first transmitter will be successfully received at the receiver.
A receiver as claimed in any preceding claim wherein the probability density function representing the likelihood that a transmission from the first transmitter will be successfully received at the receiver is an approximation which simplifies processing.
A receiver as claimed in any preceding claim wherein the transmitters are not permanent infrastructure.
A method of calculating the position of a receiver by communication with a plurality of transceivers comprising the steps of, for each of said plurality of transmitters, convolving
- (i) the probability density function representing the position of a transmitter, sent by the transmitter to the receiver;
- with
- (ii) the probability density function representing the likelihood that a transmission from the transmitter will be successfully received at the receiver
- and combining the plurality of convolution products.
